Correlation Analysis of Two Skewed Dipoles Using Embedded Beam Patterns

Progress In Electromagnetics Research C, Vol. 86, 137-152, 2018
Abstract
In this paper, the correlation coefficients of skewed dipole arrays for antenna diversity are analyzed theoretically for each polarization characteristic and in various propagation environments. The correlation is not simply increased by two closely located antennas with different polarization characteristics and it is not decreased by increased antenna distance. This result is interpreted from the correlation analysis of two skewed dipoles with different polarization characteristics. The embedded beam patterns of the two skewed dipoles are calculated using the mutual impedances derived using the effective length vector (ELV) method; then, the mutually coupled correlation coefficients for θ, ϕ, and total polarizations are effectively derived. The correlations are also analyzed for various realistic propagation environments using statistical channel models with angular density functions and cross polarization discriminations (XPDs). Finally, this paper provides an effective correlation analysis for two dipoles and proposes optimal geometries for the two skewed dipoles in various propagation environments for each polarization characteristic and with environmental variables.
